A coupling member subassembly for use in a controllable coupling assembly and an electromechanical apparatus having a pair of simultaneously actuated elements for use in such a subassembly are provided. The apparatus includes a housing, an electromagnetic source having at least one excitation coil surrounded by the housing and a pair of spaced first and second elements. A reciprocating armature is arranged concentrically relative to the at least one excitation coil and is axially movable when the at least one excitation coil is supplied with current. An actuator bridge is mounted for axial reciprocating movement with the armature and is connected to the elements at opposite ends of the bridge to move the elements in unison between first and second positions during axial movement of the armature to control the operating mode of the assembly.

The apparatus as claimed in claim 1, wherein the first element is a locking element. 3. The apparatus as claimed in claim 2, wherein the locking element is an injection molded strut. 4. The apparatus as claimed in claim 1, wherein the at least one coil, the housing and the armature comprise a low profile solenoid. 5. The apparatus as claimed in claim 1, wherein the storage element includes a rigid insert having an elastomeric layer surrounding the insert. 6. The apparatus as claimed in claim 5, wherein the elastomeric layer is a high temperature-resistant layer molded over the insert. 7. The apparatus as claimed in claim 5, wherein the insert is a die casting formed in a metal injection molding (MIM) process. 8. The apparatus as claimed in claim 1, wherein the storage element carries elastomeric material defining opposite end sections of the storage element, the end sections being configured to deflect upon abutting engagement with load-bearing shoulders of coupling members of the coupling assembly. 9. The apparatus as claimed in claim 1, further comprising at least one return biasing member to urge the bridge to a return position which corresponds to second positions of the elements. 10. The apparatus as claimed in claim 1, wherein the housing has an axially extending skirt to attach the apparatus to a first or second member of the coupling assembly. 11. An electromechanical apparatus including a pair of simultaneously actuated elements for use in a controllable coupling assembly, the apparatus comprising: a housing;an electromagnetic source including at least one excitation coil surrounded by the housing;a pair of spaced first and second elements;a reciprocating armature arranged concentrically relative to the at least one excitation coil and being axially movable when the at least one excitation coil is supplied with current:an actuator bridge mounted for axial reciprocating movement with the armature and connected to the elements at opposite ends of the bridge to move the elements in unison between first and second positions during axial movement of the armature to control the operating mode of the coupling assembly; andwherein the bridge includes a pair of plungers supported at opposite ends of the bridge and wherein the elements are pivotally connected to leading ends of their respective plungers. 12. The apparatus as claimed in claim 11, further comprising a pair of biasing members, each of the biasing members biasing its respective plunger and connected element. 13. The apparatus as claimed in claim 11, wherein each element includes at least one projecting leg portion which provides an attachment location for the leading end of its respective plunger. 14. The apparatus as claimed in claim 13, wherein each leg portion has an aperture and wherein the apparatus further comprises a pivot pin received within each aperture to allow rotational movement of the elements in response to axial movement of the bridge and wherein the leading ends of the plungers are connected to their respective elements via the pivot pins. 15. The apparatus as claimed in claim 14, wherein each aperture is an oblong aperture to receive its respective pivot pin to allow both rotational and translational movement of the elements in response to reciprocating movement of the armature. 16. A coupling member subassembly for use in a controllable coupling assembly having multiple operating modes, the subassembly comprising: a first coupling member of the assembly supported for rotation relative to a second coupling member of the assembly about a common rotational axis, the first coupling member having a first coupling face with a pair of angularly-spaced pockets, each of the pockets defining a load-bearing first shoulder; andan electromechanical apparatus attached to the first coupling member and including: a housing;an electromagnetic source including at least one excitation coil at least partially surrounded by the housing;a pair of spaced first and second elements received within their respective pockets in a first position and movable outwardly from the pockets to a second position to couple the coupling members together in an operating mode of the assembly, the second position being characterized by abutting engagement of the first and second elements with respective shoulders of the members;a reciprocating armature arranged concentrically relative to the at least one excitation coil and being axially movable when the at least one excitation coil is supplied with current; andan actuator bridge mounted for axial reciprocating movement with the armature and being connected to the elements at opposite ends of the bridge to move the elements in unison between the first and second positions during axial movement of the armature to control the operating mode of the assembly. 17.
